78 Cordoba where is the flasher unit for turn signals?

I've never seen using two before. I pulled the one and replaced it with a LED compatible flasher unit and the hazards work fine. I cannot find a second flasher unit. Unless it's drastically different in shape from the hazard flasher? There's a narrower and longer metal cylinder right next to the hazard flasher that is three prong but has no part number on it and neither the manual nor the Hanes guide gets specific enough. I replaced all bulbs with LED so I know I had to get a LED compatible flasher. Now the hazards work great but what about these turn signals? Thanks for your help in advance!
